Cisco® 3900 Series Integrated Services Routers develop on 25 decades of Cisco innovation and merchandise leadership. The new Cisco Integrated Companies Routers Generation two (ISR G2) platforms are architected to permit the following phase of branch-office environment evolution, supplying loaded-media collaboration and virtualization to the branch place of work whilst maximizing operational price personal savings. The new routers support new high-capacity electronic sign processors (DSPs) for potential increased video clip abilities, significant-powered service modules with improved availability, multicore CPUs, Gigabit Ethernet switching with Cisco Improved Electric power in excess of Ethernet (ePoE), and new electricity visibility and management features even though maximizing over-all system functionality. Furthermore, a new Cisco IOS® Computer software Common image and Cisco Services Ready Engine (SRE) module help you to decouple the deployment of hardware and software program, providing a adaptable know-how foundation that can rapidly adapt to evolving community necessities. Total, the Cisco 3900 Series offers extraordinary total cost of ownership (TCO) financial savings and network agility through the smart integration of current market-major safety, unified communications, wi-fi, and application expert services.

The Cisco 3900 Series builds on the greatest-in-class providing of the active Cisco 3800 Series Integrated Companies Routers by now supplying 4 platforms (Figure one): the Cisco 3945E, Cisco 3925E, Cisco 3945, and Cisco 3925 Integrated Providers Routers. The Cisco 3900 Series presents embedded components encryption acceleration, voice- and video-capable DSP slots, optional firewall, intrusion prevention, phone processing, voicemail, and application companies. In addition, the platforms help the industry's widest assortment of wired and wireless connectivity choices these kinds of as T1/E1, T3/E3, xDSL, copper, and fiber Gigabit Ethernet. The Cisco 3900 Series presents superior overall performance and flexibility for versatile network deployments from little organization places of work to big business offices - all even though delivering industry-foremost expense defense.

• The Cisco 3900 Series routers offer greater amounts of providers integration with voice, video, protection, mobility, and info providers. • The Cisco 3900 Series delivers the best overall performance and slot densities amid the routers in the Cisco ISR G2 portfolio, enabling you to maximize services integration and cutting down all round richesse expenses (CapEx) and functioning bills (OpEx).

• A single Cisco IOS Computer software Common picture is mounted on each and every Cisco ISR G2. The Common image includes all of the Cisco IOS Software technology sets, which you can activate with a program license. With the Common picture your business can rapidly deploy innovative functions devoid of downloading a new Cisco IOS Computer software picture. Also, greater default memory is incorporated to assistance the new abilities. • The Cisco SRE enables a new operational design that allows you to reduce CapEx and deploy a variety of application expert services as needed on a solitary built-in compute services module.

High functionality with built-in solutions

• The Cisco 3900 Series enables deployment in significant-velocity WAN environments with concurrent companies enabled up to 350 Mbps. • A multigigabit material (MGF) lets higher-bandwidth module-to-module communication without having compromising router functionality.

Network agility

• Intended to address customer business necessities, the Cisco 3900 Series with the modular architecture provides improved capability and efficiency as your network requirements develop. • The Cisco Expert services Functionality Engine (SPE) modular motherboard allows upgrades to processing capability in the foreseeable future. • Dual built-in electrical power provides offer electrical power redundancy you can also configure them to provide added Cisco ePoE electric power to endpoints. • Modular interfaces offer you improved bandwidth, a range of connection alternatives, and network resiliency.

Power performance

• The Cisco 3900 Series architecture delivers electricity-savings functions that incorporate the next: • The Cisco 3900 Series delivers intelligent energy management and will allow you to management electric power to the modules based on the time of day. Cisco EnergyWise engineering will be supported in the foreseeable future. • Services integration and modularity on a simple platform allows you to complete numerous capabilities, optimizing usage of raw materials and power use. • System versatility and ongoing advancement of equally components and program features lead to a lengthier item lifecycle, decreasing all facets of the TCO - such as materials and power use. • High-efficiency electricity provides and scalable electric power intake are primarily based on your community desires.

Expense protection

• The Cisco 3900 Series maximizes investment decision safety by supporting: • Reuse of a wide array of active modules supported on the first Cisco Integrated Companies Routers to supply a decreased TCO. • A wealthy established of Cisco IOS Application features carried ahead from the primary Cisco Integrated Services Routers and delivered in a single universal picture. • The Cisco 3900 Series offers extensive development prospects as your community expands: • The SPE modular motherboard lets overall flexibility for long term upgrades. • The greatest scale for module density offers flexibility to include providers as your organization demands develop. • A 1-Gb default memory gives headroom to lessen subject upgrades.

Platform Architecture and Modularity The Cisco 3900 Series is architected to meet up with the application demands of today's branch offices with style overall flexibility for foreseeable future purposes. The modular architecture is intended to support escalating bandwidth specifications, time-division multiplexing (TDM) interconnections, and absolutely integrated power distribution to modules supporting 802.3af PoE and Cisco ePoE. Table 2 lists the architectural functions and added benefits of the Cisco 3900 Series.

• The Cisco 3900 Series routers are hugely modular platforms with a number of kinds of module slots to add connectivity and companies for diverse branch-workplace network requirements. • The routers provide an industry-major breadth of LAN and WAN connectivity possibilities by means of modules to accommodate industry upgrades to long term technologies with out demanding system replacement. • The Cisco SPE on the Cisco 3900 provides the capacity to enhance the performance of the router with a area-upgradable motherboard as your network demands expand.

Processors

• The Cisco 3900 Series routers are driven by large-functionality multicore processors that can assist the increasing demands of higher-velocity WAN connections to the department place of work though also running multiple concurrent solutions.

Embedded IP Safety with Safe Sockets Layer (IPSec/SSL) VPN components acceleration

• Embedded components encryption acceleration is enhanced to provide bigger scalability, which, merged with an optional Cisco IOS Program Protection license, allows WAN hyperlink protection and VPN services (both equally IPSec and SSL acceleration). • The onboard encryption hardware outperforms the superior integration modules (AIMs) of past generations.

Multigigabit fabric (MGF)

• The Cisco 3900 Series introduces an progressive MGF that makes it possible for for successful module-to-module conversation, enabling tighter solutions interactions throughout modules though reducing the overhead on the router processor.

TDM interconnectivity fabric

• Unified communications expert services in the department place of work are appreciably improved with the use of TDM interconnectivity cloth in the router architecture, letting for scaling of DS- channel potential.

Integrated Gigabit Ethernet ports

• The Cisco 3900 Series gives up to four ten/a hundred/a thousand Ethernet WAN ports. • Two of the ten/a hundred/one thousand Ethernet WAN ports on the Cisco 3900 Series can help Smaller Type-Issue Pluggable (SFP)-based connectivity in lieu of RJ-forty five ports, enabling fiber connectivity.

Ground breaking common-serial-bus (USB)-based mostly console entry

• A new, modern, mini-B USB console port supports conduite connectivity when traditional serial ports are not readily available. • Traditional console and auxiliary ports are also readily available.

Optional built-in electric power supply for distribution of PoE and universal DC electrical power provide
